I am developing an android application where the user has to enter text into multiple 'edittext' boxes and then i am trying to take the entered data and save it to a text file. I have got my application to save the data from the first few boxes. I have tried many approaches such as using a for loop and others but it still doesn't work. I'm currently using an array list by adding the first few bits of data to the list, writing it to the text file, clearing the list then adding the rest of the data and trying to append that to the file.
In debugging the application gets as far as adding the first bit of the new data and stops, without crashing or any errors.
This is my code:

I'm surprised you're not seeing it crash, as it looks to me like you should be getting a NullPointerException as you don't seem to be setting the value of location. Also, it looks wrong that you're setting the value of time using the view with ID R.id.LocationText:
time = (EditText)findViewById(R.id.LocationText);
but it's difficult to be sure without knowing what you're doing exactly.

Developing a program that reads text from a file and shows it in a dynamic layout.
However, if you execute the code below, the error as below appears.

I'm currently making an app that needs to save the number and write it into a text file. But every time it writes to the file. It overwrites the last things saved. Here is the code of the entire program in java.
package com.galaxy.nestetrisscores;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import java.io.FileOutputStream;
import java.io.File;
import android.view.View;

private Button button;
private EditText editNumber;
private String file = "Scores.txt";
private String fileContents;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = findViewById(R.id.button);
editNumber = findViewById(R.id.editNumber);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
fileContents = editNumber.getText().toString();
try {
FileOutputStream fOut = openFileOutput(file, MODE_PRIVATE);
fOut.write(fileContents.getBytes());
fOut.close();
File fileDir = new File(getFilesDir(), file);
Toast.makeText(getBaseContext(), "File Saved at" + fileDir, Toast.LENGTH_LONG).show();
} catch(Exception e) {
e.printStackTrace();
}
}
});
}
}
Use the append mode when constructing the FileOutputStream.
FileOutputStream fOut = openFileOutput(file, MODE_PRIVATE | MODE_APPEND);
Not sure if this will be of any use, but a simple IF using the .exists() boolean method
File file = new File("file.txt");
if (file.exists()) {
System.err.println("File already exists");
// Append to file
} else {
// Create File
}

I'm getting a null pointer exception on the line marked with /Here/ in my code. I've spent about 2 hours looking up the AssetManager and how to use it, etc, but still can't figure out why it's null. I've called getAssets() by itself, from the context and from the resources but still I'm getting null. Can anyone help me out here?
Thanks.

You are missing setContentView(R.layout.mylayout);
#Override
public void onCreate(Bundle savedInstanceBundle){
super.onCreate(savedInstanceBundle);
setContentView(R.layout.mylayout);
Button getFactButton = (Button) findViewById(R.id.getFactButton);
findViewById looks for a resource with the id in the current inflated layout. So you should set the content of your layout to the activity before initializing views
Also you can use
res = getResources();
Instead of creating a local variable to get the Context of the Activity just use getBaseContext(); each time you want to get the reference to the Context.
So something like this instead:
AssetManager assMan = getBaseContext().getAssets();

Not sure what I am doing wrong, I tried various things and trying to look up different ways to go about doing this and none of them have worked... maybe it is something more simple than I see... the problem I think lies in the private class within this class.
I haven't read your code in great detail, but I suspect a strong contributor is this:
HttpPost httppost = new HttpPost("http://127.0.0.1:3000/wardrobe");
If you're using the emulator it's probably more likely you want to connect to "10.0.2.2". which is:
Special alias to your host loopback interface (i.e., 127.0.0.1 on your
development machine)
